I would like to know why people have chosen to study Latin. I am not looking for personal anecdotes but statistics. Are there any studies on why students who choose Latin do so? If there are several, I am ideally interested in the most broad or reliable ones. But since I don't know what is out there, I don't want to set the bar too high.
Notice that I would like to know why people choose to study Latin, not why they do study Latin. A large number of students — teachers or Romance languages, for example — will have to take a course or two in Latin whether they want it or not. My interest here is in willful choice of Latin, not compulsory. I can imagine several different reasons (had to take one course and fell in love, need to use Latin for other interests like philosophy, interest in Roman culture or history, just happening to like the language, thinking it is cool, trying to avoid PE, disliking other language options, …), but it is hard to tell which reasons are most important.
